Description

Technical Field

[0001] The invention relates to the technical field of rubber radiation processing, in particular to an electron accelerator beam device for tension-free radiation processing of rubber. Background Art

[0002] The last step in most traditional rubber processing requires vulcanization. The traditional vulcanization process uses heating and adding chemical additives to form a cross-linked structure in the rubber molecules. Electron beam continuous vulcanization uses a high-speed electron beam emitted by an electron beam device to irradiate the rubber semi-finished product, ionizing and activating the rubber compound and producing a cross-linking reaction. Compared with the traditional vulcanization process, the electron beam vulcanization process can improve product performance and is more environmentally friendly.

[0003] For example, prior art 1 (publication number: CN104723483A) and prior art 2 (publication number: CN102729373B) both use multiple sets of rollers to transport rubber sheets. This method can only irradiate one side of the rubber sheet. When the rubber is thick, the penetration depth of the electron beam in the rubber will be limited, resulting in the inability to uniformly irradiate the rubber. At the same time, for some rubber products with special shapes and structures, there will be irradiation blind spots.

[0004] Furthermore, since multiple sets of rollers are provided, loading and unloading of rubber products is inconvenient and efficient operation cannot be performed.

[0005] In summary, the current existing technology still has defects and needs to be improved. Summary of the Invention

[0006] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0007] Therefore, the object of the present invention is to provide an electron accelerator beam device for tension-free irradiation processing of rubber, comprising a housing, an electron accelerator arranged on the housing, and a winding roller, an unwinding roller and a guide roller for conveying rubber sheets.

[0008] It also includes a first driving mechanism for driving the winding roller to move horizontally, a second driving mechanism for driving the unwinding roller and the guide roller to move horizontally, and a rotating mechanism for driving the winding roller, the unwinding roller and the guide roller to rotate.

[0009] The first driving mechanism includes a first guide rail and a first screw rod, a first slider matched with the first guide rail, and a first nut sleeve matched with the first screw rod. The first nut sleeve is welded and fixed to the first slider. A first fixed frame is movably connected to the first slider. The side wall of the first fixed frame is movably connected to a bearing at one end of the winding roller.

[0010] The second driving mechanism includes a second guide rail and a second screw rod, a second slider matched with the second guide rail, and a second nut sleeve matched with the second screw rod. The second nut sleeve is welded and fixed to the second slider. A second fixed frame is fixed on the second slider. A mounting plate is welded and fixed to the side wall of the second fixed frame. The bottom end of the mounting plate is movably connected to the bearing at one end of the unwinding roller, and the top end of the mounting plate is connected to a group of guide rollers with a bearing.

[0011] As the preferred technical solution:

[0012] As described above, in an electron accelerator beam device for tension-free irradiation processing of rubber, one end of the shell is open, the open end of the shell is sealed with a side plate, four guide rods distributed in a rectangular shape are welded and fixed to the inner side surface of the side plate, and four guide cylinders that cooperate with the guide rods are welded and fixed to the inner wall of the open end of the shell.

[0013] Through the above technical solution, the guide rod is inserted into the guide cylinder, and the guide rod can slide linearly in the guide cylinder, so that the side plate can move horizontally. In this way, the side plate and the shell are driven to fit or separate manually or by power equipment, which facilitates rapid loading and unloading.

[0014] As described above, in an electron accelerator beam device for tension-free irradiation processing of rubber, a group of insertion rods and a group of fixing cylinders are welded and fixed on the inner wall of the shell, a group of third gears are provided inside the shell, the third gear bayonet is fixed on the rotating rod, and one end of the rotating rod passes through the shell and is connected to the first motor.

[0015] Through the above technical solution, the first motor is fixed on the outer wall of the shell, and the rotating rod is movably connected to the shell bearing, so that the first motor can drive the third gear to rotate axially through the rotating rod. The first motor is a non-brake motor. When the first motor is not running, the third gear can rotate freely under the action of external force. In this way, when the first gear moves horizontally, it can push the third gear to rotate and complete the engagement with the third gear.

[0016] The above-mentioned device for tension-free irradiation processing of rubber under an electron accelerator beam comprises a rotating plate and a gear ring sleeved and fixed on the outer wall of the rotating plate. The side surface of the rotating plate is welded and fixed to the first guide rail and one end of the second guide rail. The gear ring is engaged with the second gear. The second gear is fixed to the output shaft of the second motor by a bayonet.

[0017] The side plate is provided with a through slot for the rotating plate to penetrate, and the outer circular wall of the rotating plate is movably connected to the slot wall bearing of the through slot.

[0018] Through the above technical solution, the rotating plate and the through slot are both circular, so that the rotating plate can rotate axially along the through slot, and then the first guide rail and the second guide rail can rotate synchronously with the rotating plate.

[0019] In the electron accelerator beam device for tension-free irradiation processing of rubber as described above, the ends of the first and second guide rails not connected to the rotating plate are provided with slots adapted to the insertion rods, and the slots are coaxial with the insertion rods.

[0020] Through the above technical solution, after the first guide rail and the second guide rail are inserted into the shell, the insertion rod can be inserted into the slot. In this way, the insertion rod can cooperate with the rotating plate to support the first guide rail and the second guide rail, ensuring that the first guide rail and the second guide rail can remain horizontal, thereby improving the movement accuracy of the winding roller, unwinding roller and guide roller.

[0021] As described above, in the electron accelerator beam device for tension-free irradiation processing of rubber, a group of vertical rods are welded and fixed to the top of the first slider, the tops of the vertical rods pass through the first fixed frame, and elastic springs are sleeved on the vertical rods. The two ends of the elastic springs are welded and fixed to the first slider and the first fixed frame.

[0022] Through the above technical solution, the vertical rod and the first fixing frame are attached and not fixed, and then the first fixing frame can move up and down along the vertical rod.

[0023] As described above, in an electron accelerator beam device for tension-free irradiation processing of rubber, one end of the first screw rod and the second screw rod both pass through the rotating plate and are movably connected to the rotating plate bearing, one end of the first screw rod is connected to the third motor, and one end of the second screw rod is connected to the fourth motor.

[0024] Through the above technical solution, the third motor and the fourth motor are both fixed on the outer surface of the rotating plate, and thus the third motor and the fourth motor can rotate synchronously with the rotating plate.

[0025] In the above-mentioned device for tension-free irradiation processing of rubber under an electron accelerator beam, the diameters of one end of the first screw rod and the second screw rod are consistent with the inner diameter of the fixed tube, and the two fixed tubes are coaxial with the first screw rod and the second screw rod respectively.

[0026] Through the above technical solution, after the first screw rod and the second screw rod are inserted into the shell, one end of the first screw rod and the second screw rod can be inserted into the fixed cylinder, and the fixed cylinder cooperates with the rotating plate to support the first screw rod and the second screw rod, ensuring that the first screw rod and the second screw rod can remain horizontal, thereby improving the movement accuracy of the winding roller, unwinding roller and guide roller.

[0027] As described above, a device under an electron accelerator beam for tension-free irradiation processing of rubber has grooves on the bottom surfaces of both sides of the first fixed frame, rollers are movably connected in the grooves, a bottom plate is welded and fixed to the bottom end of the first guide rail, a group of lifting bars are welded and fixed to the surface of the bottom plate, and one end of the lifting bar has a slope.

[0028] Through the above technical solution, the roller contacts the surface of the bottom plate, and when the first fixed frame moves horizontally, the roller can roll on the surface of the bottom plate.

[0029] In the electron accelerator beam device for tension-free irradiation processing of rubber as described above, a first gear is fixed to one end of the winding roller, and the first gear and the third gear are on the same vertical plane.

[0030] Through the above technical solution, when the winding roller moves horizontally back and forth, the first gear on it can contact and engage with the two third gears after moving, and then the third gear cooperates with the first gear to drive the winding roller to rotate.

[0031] Beneficial effects:

[0032] (1) The present invention provides an electron accelerator beam device for tension-free irradiation processing of rubber, which is provided with a winding roller, an unwinding roller and a guide roller. The three rollers cooperate with each other to convey the rubber sheet to continuously move from under the electron accelerator, and then the electron accelerator generates a high-speed electron beam to irradiate the rubber sheet to achieve vulcanization treatment of the rubber sheet. During the entire irradiation process, no tension control is required, and tension-free irradiation operation can be achieved;

[0033] (2) The electron accelerator beam device for tension-free irradiation processing of rubber of the present invention is provided with a first driving mechanism and a second driving mechanism. After the front side of the rubber is irradiated and vulcanized, the first driving mechanism drives the winding roller to move toward the left side, and the second driving mechanism drives the unwinding roller and the guide roller to move toward the right side. In this way, the reverse side of the rubber sheet can be switched to face upward, thereby realizing double-sided irradiation of the rubber sheet. This design is not only simple in structure and easy to operate, but also effectively ensures the irradiation effect of the rubber.

[0034] (3) The electron accelerator beam device for tension-free irradiation processing of rubber of the present invention has a structure in which the winding roller, unwinding roller and guide roller can move horizontally. When the three rollers move to one side and are removed from the open end of the shell, the rubber sheet can be quickly placed on the unwinding roller and the vulcanized rubber sheet can be removed from the winding roller, thereby reducing the loading and unloading time and improving the working efficiency.

[0035] (4) The electron accelerator beam device for tension-free irradiation processing of rubber of the present invention is provided with a rotating mechanism. During the irradiation process of the rubber, the rotating mechanism drives the winding roller, the unwinding roller and the guide roller to rotate, thereby driving the rubber to rotate synchronously. In this way, the rubber can be irradiated at different angles, further improving the irradiation effect and enhancing the product performance. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0047] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0048] like Figures 1-8 As shown, the embodiment of the present invention discloses an electron accelerator beam device for tension-free irradiation processing of rubber, comprising a housing 1, an electron accelerator 3 arranged on the housing 1, and a winding roller 19, an unwinding roller 23 and a guide roller 24 for conveying rubber sheets.

[0049] The utility model further comprises a first driving mechanism for driving the winding roller 19 to move horizontally, a second driving mechanism for driving the unwinding roller 23 and the guide roller 24 to move horizontally, and a rotating mechanism for driving the winding roller 19, the unwinding roller 23 and the guide roller 24 to rotate.

[0050] The first driving mechanism includes a first guide rail 4 and a first screw rod 8, a first slider 6 matched with the first guide rail 4, and a first nut sleeve 10 matched with the first screw rod 8. The first nut sleeve 10 is welded and fixed to the first slider 6. A first fixed frame 14 is movably connected to the first slider 6. The side wall of the first fixed frame 14 is movably connected to the bearing at one end of the winding roller 19.

[0051] The second driving mechanism includes a second guide rail 5 and a second screw rod 9, a second slider 7 matched with the second guide rail 5, and a second nut sleeve 11 matched with the second screw rod 9. The second nut sleeve 11 is welded and fixed to the second slider 7. A second fixed frame 21 is fixed to the second slider 7. A mounting plate 22 is welded and fixed to the side wall of the second fixed frame 21. The bottom end of the mounting plate 22 is movably connected to a bearing at one end of the unwinding roller 23. The top end of the mounting plate 22 is connected to a group of guide rollers 24 with a bearing.

[0052] The rotating mechanism includes a rotating plate 27 and a gear ring 28 sleeved and fixed on the outer wall of the rotating plate 27. The side of the rotating plate 27 is welded and fixed to the first guide rail 4 and one end of the second guide rail 5. The gear ring 28 is engaged with the second gear 29, and the second gear 29 is fixed to the output shaft of the second motor with a pin.

[0053] The side plate 2 is provided with a through slot 26 for the rotating plate 27 to penetrate. The outer wall of the rotating plate 27 is movably connected to the groove wall bearing of the through slot 26.

[0054] One end of the shell 1 is open, and the open end of the shell 1 is sealed with a side plate 2. Four rectangularly distributed guide rods 32 are welded and fixed on the inner side of the side plate 2. Four guide cylinders 33 that cooperate with the guide rods 32 are welded and fixed on the inner wall of the open end of the shell 1.

[0055] Specifically, such as Figure 1As shown, before the operation, the side plate 2 is driven to move horizontally by manual pushing and pulling or power equipment. When the side plate 2 moves and separates from the shell 1, the first guide rail 4 and the second guide rail 5 can be driven to move horizontally synchronously by the rotating plate 27. At this time, the winding roller 19, the unwinding roller 23 and the guide roller 24 are driven to move to the open end side of the shell 1 by the first driving mechanism and the second driving mechanism, so that it is convenient to load the rubber sheet onto the unwinding roller 23, and then pull the rubber sheet through the two guide rollers 24 and wind it around the winding roller 19, and finally the side plate 2 moves to fit tightly with the shell 1. The side plate 2 and the shell 1 are made of metal material with shielding effect, so that shielding and protection can be performed during electron beam irradiation operation. At the same time, in order to ensure the irradiation effect, inert gas can be injected into the shell 1 during the irradiation process.

[0056] When the front side of the rubber needs to be irradiated, such as Figure 2 As shown, when the first screw rod 8 rotates clockwise, the first nut sleeve 10 can push the first slider 6 to slide along the first guide rail 4. When the first slider 6 slides, the first fixed frame 14 can drive the winding roller 19 to move synchronously. The winding roller 19 can pull the rubber sheet and continuously wind it. In this way, the rubber sheet faces upward and continuously moves under the electron accelerator 3. The electron accelerator 3 generates a high-speed electron beam that can continuously irradiate the rubber sheet.

[0057] When the rubber front is irradiated, Figure 3 As shown, the first screw rod 8 rotates counterclockwise, and pushes the first slider 6 to slide along the first guide rail 4 through the first nut sleeve 10. When the first slider 6 slides, it can drive the winding roller 19 to move in the opposite direction through the first fixed frame 14. At the same time, the second screw rod 9 rotates clockwise, and can push the second slider 7 to move horizontally along the second guide rail 5 through the second nut sleeve 11. The second slider 7 drives one side of the mounting plate 22 through the second fixed frame 21, and the mounting plate 22 drives the unwinding roller 23 and the guide roller 24 to move synchronously. At this time, the winding roller 19, the unwinding roller 23 and the guide roller 24 cooperate with each other to drive the reverse side of the rubber sheet upward. At this time, the winding roller 19 continues to pull the rubber sheet and continuously winds it, so that the reverse side of the rubber sheet faces upward and continuously moves under the electron accelerator 3. The electron accelerator 3 generates a high-speed electron beam that can continuously irradiate the rubber sheet.

[0058] During the irradiation of rubber sheets, Figure 6As shown, the second motor is fixed on the side plate 2. After the second motor is powered on, it can drive the second gear 29 to rotate. The second gear 29 can drive the rotating plate 27 to rotate axially in the through groove 26 by engaging with the ring gear 28. The rotating plate 27 can drive the first guide rail 4 and the second guide rail 5 to rotate by axially rotating on the side plate 2, thereby driving the rubber sheet to rotate as a whole through the winding roller 19, the unwinding roller 23 and the guide roller 24, so that the rubber sheet can be irradiated from different angles. The first driving mechanism, the second driving mechanism and the rotating mechanism cooperate with each other to ensure uniform irradiation and good vulcanization effect, which is beneficial to improving the performance of the product and improving the scope of application of the device. Thicker rubber sheets and rubber semi-finished products with special shaped structures can be vulcanized.

[0059] In a specific embodiment of the present invention, a group of insertion rods 35 and a group of fixing cylinders 36 are welded and fixed on the inner wall of the housing 1. A group of third gears 30 are provided inside the housing 1. The third gear 30 is fixed to the rotating rod 31 by a bayonet. One end of the rotating rod 31 passes through the housing 1 and is connected to the first motor. The first gear 20 is fixed to one end of the winding roller 19. The first gear 20 and the third gear 30 are on the same vertical plane.

[0060] One end of the first screw rod 8 and the second screw rod 9 both pass through the rotating plate 27 and are movably connected to the bearing of the rotating plate 27. One end of the first screw rod 8 is connected to the third motor, and one end of the second screw rod 9 is connected to the fourth motor.

[0061] Specifically, such as Figure 1 、 Figure 4 and Figure 8 As shown, the first motor, the second motor, the third motor and the fourth motor are all located outside the housing 1, so that the interior of the housing 1 will not be affected by the four motors when the electron beam is irradiated, and the operation of the four motors will not be disturbed.

[0062] The first screw rod 8 and the second screw rod 9 are both controlled by separate motors, so that the horizontal movements of the winding roller 19, the unwinding roller 23 and the guide roller 24 do not interfere with each other, and the structure is reasonable.

[0063] After the winding roller 19 moves horizontally to the left or right, the first gear 20 on it can contact and engage with the corresponding third gear 30. Then, when the first motor is powered on, the first motor drives the third gear 30 to rotate through the rotating rod 31. The third gear 30 can drive the winding roller 19 to rotate by engaging with the first gear 20. The winding roller 19 can realize continuous irradiation operation by winding the rubber sheet.

[0064] In one embodiment of the present invention, a slot 34 adapted to the insertion rod 35 is provided at one end of the first guide rail 4 and the second guide rail 5 that is not connected to the rotating plate 27. The slot 34 and the insertion rod 35 are coaxial.

[0065] The diameters of one end of the first screw rod 8 and the second screw rod 9 are consistent with the inner diameter of the fixed cylinder 36 , and the two fixed cylinders 36 are coaxial with the first screw rod 8 and the second screw rod 9 respectively.

[0066] Specifically, such as Figure 5 and Figure 8 As shown, the first guide rail 4 and the second guide rail 5, the first screw rod 8 and the second screw rod 9 are all in a suspended state. Due to the long overall span, as the winding roller 19, the unwinding roller 23 and the guide roller 24 continue to move, one side may tilt. In order to ensure that the winding roller 19, the unwinding roller 23 and the guide roller 24 can move stably, an insertion rod 35 and a fixed cylinder 36 are provided. When the side plate 2 moves to fit with the shell 1, the first guide rail 4 and the second guide rail 5, the first screw rod 8 and the second screw rod 9 move synchronously with the rotating plate 27, the insertion rod 35 can be just inserted into the slot 34, and one end of the first screw rod 8 and the second screw rod 9 can be inserted into the corresponding fixed cylinder 36. In this way, the first guide rail 4 and the second guide rail 5, the first screw rod 8 and the second screw rod 9 are supported by the insertion rod 35 and the fixed cylinder 36, so that the overall structure is more stable and reliable.

[0067] In a specific embodiment of the present invention, grooves 16 are formed on the bottom surfaces of both sides of the first fixed frame 14, and rollers 15 are movably connected in the grooves 16. A bottom plate 25 is welded and fixed to the bottom end of the first guide rail 4, and a group of lifting bars 17 are welded and fixed to the surface of the bottom plate 25. One end of the lifting bar 17 has a slope 18.

[0068] A set of vertical rods 12 are welded and fixed to the top of the first slider 6. The top of the vertical rods 12 passes through the first fixed frame 14. An elastic spring 13 is sleeved on the vertical rods 12. Both ends of the elastic spring 13 are welded and fixed to the first slider 6 and the first fixed frame 14.

[0069] Specifically, such as Figure 4 、 Figure 5 and Figure 7As shown, when the first slider 6 moves along the first guide rail 4, the first slider 6 will drive the first fixed frame 14 to move synchronously through a group of vertical rods 12, and the rollers 15 on the first fixed frame 14 will roll on the surface of the bottom plate 25. During the rolling process, the rollers 15 will roll to the top surface of the lifting bar 17 through the inclined surface 18, and then the lifting bar 17 can lift the height of the first fixed frame 14 upward through the rollers 15. At this time, the first fixed frame 14 moves vertically upward along the vertical rod 12 and stretches the elastic spring 13. This design makes it possible to avoid the winding roller 19 and the guide roller 24 from colliding with each other by raising the height of the winding roller 19 when the winding roller 19, the unwinding roller 23 and the guide roller 24 move towards each other.

[0070] After the winding roller 19 moves in the opposite direction again, the roller 15 will separate from the lifting bar 17. At this time, under the elastic force of the elastic spring 13, the first fixed frame 14 will be pulled to reset, thereby restoring the winding roller 19 to its original height.

[0071] In this specification, terms such as "connect," "install," and "fix" should be understood broadly. For example, "connect" can mean a fixed connection, a detachable connection, or an integral connection; it can mean a direct connection or an indirect connection through an intermediary. A person of ordinary skill in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0072] Throughout this specification, terms such as "one embodiment," "some embodiments," and "specific embodiments" mean that the specific features, structures, materials, or characteristics described in conjunction with that embodiment or example are included in at least one embodiment or example of the present invention.
